As shown in the figure, inter-AS VPN Option A is used. CE 1 and CE 2 belong to the same VPN.AS 100 and AS 200 run IGP and LDP, respectively. ASBRs communicate with each other through EBGP. The loopback interface address of CE 1 is 10.1.1.1/24. Suppose CE 2 can ping CE 1. Which router allocates an inner label when PE 2 forwards packets from CE 2 to CE1?

A. PE 1

B. P1

C. ASBR 1

D. ASBR 2

E. P2

User A want to obtain a better network service for business development and signs an SLA with a corner. User A purchases a bandwidth of 5 Mbit/s to ensure the voice service (requiring short delay), vide service, key data services, and other services, If you were corner network administrator.

What would you do on the PE to ensure these services?

A. Mark the VoIP service as EF, set the CIR to 0Mbit/s, and set the PIR to 1 Mbit/s mark the video service as AF 4 and set the CIR and PIR to 2 Mbit/s mark key data services as AF3, set the CIR to 1 Mbit/s and the PIR to 5 Mbit/s: mark other services as AF1, set the CIR to 2 Mbit/s and Set PIR to 5 Mbit/s.

B. Mark the VoIP service as EF, set the CIR to 0Mbit/s, and set the PIR to 1 Mbit/s mark the video service as AF 4 and set the CIR and PIR to 2 Mbit/s mark key data services as AF3, set the CIR to 1 Mbit/s and the PIR to 5 Mbit/s: mark other services as AF1, set the CIR to 2 Mbit/s and Set PIR to 5 Mbit/s.

C. Mark the VoIP service as EF, set the CIR to 1 0Mbit/s, and set the PIR to 1 Mbit/s mark the video service as AF 4 and set the CIR and PIR to 2 Mbit/s mark key data services as AF3, set the CIR to 2 Mbit/s and the and the PIR to 5 Mbit/s : mark other services as BE, set the CIR to 0 Mbit/s and set PIR to 5 Mbit/s.

D. Mark the VoIP service as EF, set the CIR to 2 Mbit/s: marks the video service as AF 3 and set the CIR and PIR to 2 Mbit/s: mark key data services as AF4, set the CIR to 2 Mbit/s and the PIR to 5 Mbit/s mark other service as BE, set the CIR to 0 Mbit./s and set PIR to 5 Mbit/s

Exhibit.

As shown in the figure, OSPF process 100 runs on both PEs and CEs, and VPN routers are transmitted between PE 1 and PE 2 through PGB CE 1 enables interface address 43.1.1.0/24 in area 0.A route to 43.1.10/24. However, does not exist in the routing table of CE 2. What are the possible causes?

A. The VPN route to 43.1.1.0/24 does not exist in the routing table of PE 2.

B. The LSDB of PE 1 does not have the type 1 LSA generated by CE 1.

C. The LSDB of PE 12 does not have the type 1 LSA generated by CE 1.

D. The public network rout to 43.1.1.0/24 does not exist in the routing table of PE2 .

RTA is a leaf router that directly connects to host A through interface GigabiteEthernet 1/0/0. The interface is configured as follows:

Hos a sends a IGMPv2 Report message to group 2321.2.3. Which entry can be displayed by the displayed by the igmp ssm-mapping group command?

A. (10.10.1.1, 232.1.2.2)

B. (10.10.1.1, 232.1.1.) and (10.10.1., 2321.2.3)

C. (10.10.1.1, 232.1.1.1)

Exhibit.

A. Deletes the record of group 224.1.2.3

B. Sends group-specific query messages for group 224.1.2.4

Which statement about the configuration of route target (RT) and route distinguisher (RD) is true?

A. If routes need to exchange between two VPNs, the value of import RT of one VPN must be partially the same as Export RT of the other VPN.

B. RD and RT of a VPN instance cannot be the same as those of another VPN instance on the same PE.

C. If routers need to exchanged two VPNs, the value of import RT of one of the same as that of RT of the other VPN.
